Pentatonix's Brilliant A Cappella Rendition Of 'Carol Of The Bells' Wins Christmas (VIDEO)

Well, Pentatonix is back to take over the holidays again, this time with a beautiful rendition of "Carol of the Bells." The a cappella singers performed the track on "Conan," Conan O'Brien's late-night show.

The five performers are using only their voices to create the magical moment. (The track is off the group's "PTXmas" album.)

It's really hard to get sick of these guys when they keep coming out with the best musical additions to our Christmas mixes!
